Before the release of the HTC One X, S and V, HTC was making the rounds, touting Sense 4.0 as the lightest, leanest version of their Android skin ever. We were inclined to believe them after seeing how zippy and kicky fast Sense was, not only real world usability tests, but in benchmarks as well.

As it turns out, Sense may not be as lean as we once thought. The internet has been abuzz recently, after a user uploaded a video showcasing a uniquely Sense 4.0 multitasking issue, in which the HTC One X will keep only a very minimal amount of apps paused in the background. The result are apps that fall out of RAM, and need to reloaded when revisiting them each time.

HTC’s response? It’s “Sense optimized.” And that’s just the way they like it. The boys at HTC issued this official statement on the matter:

HTC is aware of some questions in the enthusiast community about how the HTC One X handles multitasking and memory management for background apps. We value the community’s input and are always looking for ways to enhance customers’ experience with our devices. That said, right now multitasking is operating normally according to our custom memory management specifications which balance core ICS features with a consistent HTC Sense experience.

You may remember Android’s early development years in which devs attempted to port Sense to less.. RAM worthy devices. Homescreen reloads plagued those ROMs, and I’m sure this was something HTC was looking to avoid when tweaking the software on their new One series devices. Sense gets first priority, and that’s the way it’s going to stay. Just goes to show that 1GB of RAM isn’t as ample as we once thought. Bring on the 2 gee-bee’s!
